Found out that is has the same board as the Taramps 3000hd. But on an amp dyno, it produced 1000w less certified @1ohm. I wish I had one of each, to find out why the audiopipes version is weaker. Has anyone had a chance to play with one yet?
It could be the rail voltage is different between the two. I couldn't find any detailed information on the Audiopipe.
Could the H1 indicate that it's a high voltage amp and needs 16v to produce the power you expect?
Perry, through some online researching. I have found that the audiopipe version uses IrF1404 input mosfets, and the Taramps uses CSD18502KCS input mosfets.
I think you're referring to the power supply FETs. Except for reliability, they have very little to do with anything. Power output is determined by the rail voltage and the load the amp is driving. The rail voltage is determined by the transformer winding ratio, and to some degree, regulation, if the rail voltage is regulated.
